Method Detail

validate

public void validate(IFormComponent field,

              throws ValidatorException

Does comparison based on the Number.doubleValue().

Parameters:

field - the form element component being validated, often used to determine the user presentable name for the field, used in error messages.

messages - access to the pre-defined validation messages, in the appropriate locale

object - the client-side representation of the field's data. May be null if the client did not provide a value for the field (most Validators should check for null and perform no check if null).

Throws:

ValidatorException - if the object violates the constraint represented by this Validator.
